ARLX013 Solar Eclipse QSO Party Seeks Amateurs and Radio Enthusiasts
for Global Experiment

ARRL is proud to partner with HamSCI to help promote participation
in the Solar Eclipse QSO Party (SEQP). SEQPs are a series of global
experiments -- and you can be a part of them. Solar eclipses will
pass across the continental United States on October 14, 2023, and
April 8, 2024.

During these celestial events, you can join thousands of fellow
amateurs as part of the largest crowd-sourced event for ham radio
scientific exploration. The SEQP is part of the Festivals of Eclipse
Ionospheric Science and is for learning more about how the
ionosphere works.

All radio amateurs need to do is operate using any mode and any band
for all or part of the day, then upload their logs. Participation
can be from anywhere; you don't need to be near the path of the
eclipse to contribute valuable data. You don't even have to be a
licensed ham to participate in the experiment (only to transmit).

For SEQP contest and rules, visit .

For information on the Gladstone Signal Spotting Challenge using CW,
WSPR, and FST4W, go to .

If you're an SWL or AM DXer, you might be interested in the Medium
Wave Recording Event. Go to
for more information .  Or just get on the air and help provide data
to better understand the ionosphere.

The first SEQP is on Saturday, October 14, 2023, from 1200 - 2200
UTC, and participants may use any band or mode (except WARC bands).
Researchers will take the submitted logs and work to derive
meaningful observations from the data.

ARRL members can find out more about the SEQP by reading "The Solar
Eclipse QSO Party: A Fun Way to Support Radio Science" in the
September/October 2023 issue of On the Air magazine. The On the Air
podcast will feature the article's author, Gary Mikitin, AF8A,
talking about the event. The episode will go live on October 12.
